towards the end it stopped spinning, didn’t drain, and smoke started

I know it’s been a while since anyone posted but I’m hoping someone can help me out here…I have a top-loading Kenmore Heavy Duty Plus (not sure what model number) I inherited from my mil - it must be at least 20 years old. I washed some summer blankets and it was working fine, then towards the end it stopped spinning, didn’t drain, and smoke started coming out of the machine. I’m not sure how long this was going on before I noticed it. I think the spinner thing may have gotten tangled up in the blankets. I took the blankets out and switched it to “Spin Only” and the water drained out. I then figured it was ok and put another load in. This time the water filled up, the machine made a loud humming sound and nothing else happened. I also smelled the burning smell again. Did I burn out the motor or is it something else?
